Product Description
ANALOG &DIGITAL DUAL MODES
DM-R88 can support both analog and digital modes on the same hardware. You can switch between two operation modes very smoothly and it helps you to communicate with analog radios.
ANALOG MODE, DIGITAL MODE, ANALOG+DIGITAL MODE
DM-R88 can supply you three mode, which is a real migration technology from analog to digital.
VOICE ANNOUNCEMENT
Channel number announcement helps you to switch channels quickly and correctly, even in blindness operation.
LONG WORKING TIME
Based on TDMA technology, DM-R88 support more longer standby time.
CLEAR VOICE
Excellent audio quality comes from the DMR digital technology, which makes the communication more reliable.
ANTI-INTERFERENCE
Adopted digital encoding and error correcting module, DM-R358 can have a better ability to avoid signal interference on the same frequency.
DMR SIGNALING
With DMR signaling, transmitting group call, private call and all call with PTT ID becomes quite easy.
REPEATER MODEOPERATION
Utilize a DMR Tier II repeater to extend your communication range.
VOX
When you use VOX earpiece, this feature allows you to activate the microphone via speaking volume, and free your hand from PTT.
SCANNING
Allow users listening to communication activities on other channels.
